' OF SAME PLACE.

CARPET-SWEEPER.

SPECIFICATION forming part of Letters Patent No. 248,379, dated October 18, 1881.

(ModeL) To all whom it may concern:

Be it known that I, HENRY S. WING, of Detroit,countyof Wayne, State of Michigan, have invented a new and useful Improvement in Carpet-Sweepers; andIdeclare thet'ollowing to he a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying draw- IO ings, which form a part of this specification.

My invention consists of the combinations of devices and appliances, as hereinafter described, and more particularly pointed out in the claims.

In the drawings, Figure l is a perspective view of a carpet-sweeper constructed according to my invention. Fig. 2 is an end View of the same, looking toward the wheel-chamber. Fig. 3 is a section in the plane indicated by the dotted line a: a, Fig. 1. Fig. 4 is a central vertical section of the end wall at the end of the sweeperopposite the wheel-chamber. Fig. 5 is a view of a portion of the bottom of one of the dust-pans and a portion of the lower edge of the wall to which it is pivoted,illustrating the arrangement of the bearing-blocks. Fig. 6 is a partial view of the outer wall of one of the dust-pans, showing the bearing-block out of its socket, and having the pintle of the pan 0 inserted therein, said tigure also showing a portion of the partitionwall, in which is formed the socket for said hearingblock. Figs. 7 and 8 are respectively detached views of the adjustable devices for supporting the brush-roller. My invention relates more particularly to the friction device, the htush-hangers,the peculiar method of dumping the pans, and their construction and connection with the case.

To this end A is a sweeper-case, made of any 40 suitahlematerial. A isthc friction-wheelcase, and A the opposite end. This latter end, A I prefer to form of sheet metal or other thin metal, in order that the brush-wheel may come out close to the outer surface of the sweeper, 5 and thus be brought close to the edge of the carpet when the sweeper is being used close to the wall of an apartment. This feature I regard as very important, because in the ordinary sweepers in which a wooden end board is employed the thickness of the wood holds the brushes so far away from the wall that it is impossible to sweep close to the wall. Another function may be accomplished by the making of this end wall of sheet metal i. 6.,

it will spring sufficiently to permit the brushroller to be sprung into place without other appliances.

B is the brush-roller; B, the brush-wheel, which engages the friction rollersor Wheels 0.

Dis the brush-hanger. Itconsists of aplate, 6o pivoted at d by means of a pin, d, to an arm, D, shown in dotted lines, Fig. 2, said arm being pivoted at d to the inner surface of the wall of the wheel-chamber. At its free end this arm D is provided with a pin, d which may enter any one.of a series of holes, d formed in the wall, or in a metal plate, d fixed to said wall. The pin (1 projects outwardly through a slot, (1 surrounded by a suitable plate or escutcheon, and terminates in a button or knob. By pressing the button or knob the arm D may be forced inward, its pin disengaged from any hole it may be in, and the arm adjusted up or down, as desired, its elasticity causing the pin to engage with another hole and retain the arm as adjusted.

In Fig. 1 is shown the brush-supporting plate at the opposite end of the case. It is a metallic plate, D shown in dotted lines, pivoted at d, to the inner surface of the thin endwall, and provided with a slot, (1 through which a guide-pin projects from the wall. A pin, (1 projects from the plate, and may, for the purpose of adjusting the plate, be engaged with any of a series of holes, (1 formed in the wall. This adjustment is very simple, inexpensive, and not liable to get out of order.

E represents the hanger for the friction-rolls, they each consist of a metallic loop in the ends ofwhich the wheel is journaled, as shown. The 0 hangers are pivoted at e to the case. Aspringarm, E, is rigidly attached to the plate at c, and as the opposite or free end embraces a bolt or screw, 0 which latter holds a spiral spring, E in constant pressure upon the ends of the 5 springs E, it is apparent that the spring-arm E causes the wheels 0 to press firmly against the brush-wheel, and this pressure may be varied by means of the screw 0 the whole constituting an adjustable friction. 10o

F represents the pans. They are hinged to the case atf, as shown, so that when dumped they will,at the end opposite the friction-wheel case,dropbelow the end of the case. The pans are made open at this latter end, so that the dirt may he slid out of the pans longitudinally. Springs or latches F are secured to the pans, so as to lock them up against the case, and form a thumb hold, against which to press when dumping the pans. 1 also propose to employ a spring, G, to lock the pans in either an open or closed position; but I do not here claim the same as it forms the subject-matter of another application heretofore filed by me.

H are journal blocks or boxes for receiving the piutle at the end of the dust-pans, which may or may not be employed. The positions of these blocks are indicated by dotted lines, Fig. 3, and the same more clearly shown in full lines, Figs. 5 and 6. The bearing-blocks are simply cylindrical blocks of wood,with aperture h formed in one side to receive the pan pivot orpiutle. A socket, H,is formed for each of said bearing-blocks by boring a hole upwardly in the lower edge of the partitioinvall and cutting a slot through the inner surface of the wall from said hole, to allow the passage of the pivot-pin. The object is as follows: It is usually quite diflicult to insert the pans in the case, but by this device the pintles can be inserted in the blocks or boxes and then the latter be pushed into their places and fastened; or the pindle at one end of a pan may be, as usual. inserted in a hole in the case, and the the other pintle be provided with one of these removable blocks or boxes and he slipped into place.

The handle attachment consists of a plate or plates, l,with ears t'projecting up alongside the handle-brace I, so that as the handle is raised to its vertical position the ears will yield and permit the sides of the brace to snap into the notches; butbyaslighteflort thehaudleinay be again recessed after dumping the pans. The

notches i are beveled, so as to automatically engage the handle-brace, and when it is desired to again use the sweeper the latter is brought down upon the carpet, and a downward pressure of the handle will automatically disengage it from the notches i.

I am aware that carpet-sweeper brushes have been provided with adjustable bearings, and I lay no claim to such construction.

\Vhat I claim is 1. In a carpet-sweeper, the combination,with the casing end wall having the slot and series of holes formed therein, substantially as described, of the brush-hanger consisting of the springplate pivoted at one end to the inner surface of said wall, provided iutermediately with a brush-roller bearing and with a pushbutton projecting through said slot, and having at its opposite end a pin arranged to enter the holes, substantially as described.

2. In a carpetsweepena friction device consistingofthecombinatiomwithafriction-wheel, ot' a hanger pivoted at its upper end,a springarni fastened rigidly to the hanger at its pivotal point, and in connection with the end of said arm an adjusting spring and screw,wliereby the amount of friction may be varied at will, substantially as desrcibed.

3. In a carpet-sweeper, a dust-pan having the end farthest from the friction-wheel case open, s id pan pivoted at both ends on longitu dinal pivots, so located with respect to the end of the brush-case that on dumping the pan it will drop below the case and permit the contents to be discharged through the open end, substantially as described.

i. In a carpet-sweeper having a dust-pan pivoted at both ends on longitudinal pivots,a removable journal box or block adapted to receive one of said pivots and be then slid up into its place, whereby the insertion of the dustpan is facilitated, substantially as described.

- In testimony whereof I sign this specification in the presence of two witnesses.
